I took off the detent on my friend's TES and when I screwed it back in, the knurled cap came off! I must have screwed it in too hard. I managed to get the threaded part out of the body, and we were able to press the two peices back together and screw it back in. Is it possible to screw in TOO far? Will this give him problems in the future? I would buy him a new detent if I knew where I could get one.
